constructor(imageConfig: ImageConfig = ImageConfig.RGBA_8888)

Properties

imageConfig

var imageConfig: ImageConfig

Indicates the in-memory configuration for images displayed by WorldWind components. By default, images are represented in the 32-bit RGBA_8888 configuration, the highest quality available. Components that do not require an alpha channel and want to conserve memory may use the 16-bit RGBA_565 configuration. Accepted values are ImageConfig.RGBA_8888 and ImageConfig.RGB_565.

initialHeight

var initialHeight: Int

Initial height for image that has no dimensions (e.g. SVG image)

initialWidth

var initialWidth: Int

Initial width for image that has no dimensions (e.g. SVG image)

maxDimension

var maxDimension: Int

Caps the decoded image to this maximum width/height (downsampled at decode time when possible). 0 means uncapped. Used to bound memory for large textures such as photogrammetry atlases.

resamplingMode

var resamplingMode: ResamplingMode

Indicates the image sampling algorithm used by WorldWind to display images that appear larger or smaller on screen than their native resolution. Accepted values are ResamplingMode.BILINEAR and ResamplingMode.NEAREST_NEIGHBOR.

wrapMode

var wrapMode: WrapMode

Indicates how WorldWind displays the contents of an image when attempting to draw a region outside of the image bounds. Accepted values are WrapMode.CLAMP and WrapMode.REPEAT.
